John Mayer Slams Taylor Swift as "Cheap" BS Artist

John Mayer might just wanna take Rolling Stone off his speed dial at this point.

A couple years after going off to the magazine about how he has masturbated himself "out of some serious problems in my life," the singer has once again made headline in an interview with the publication.

This time for comments aimed squarely at ex-girlfriend Taylor Swift and related to the following single, "Dear John."

"It made me feel terrible," Mayer says of the revenge-based song, whose lyrics include Swift saying she was "too young to be messed with."

Mayer says he didn't "deserve" the diss and went on to say he "never got an email [or] phone call" about his ex - John and Taylor reportedly hooked up in early 2010 - releasing the track for the world to hear.

"["Dear John" is] cheap songwriting," the artist adds "It's abusing your talent to rub your hands together and go, 'Wait til he gets a load of this!' That's bullsh-t.. I mean, how would you feel if, at the lowest you've ever been, someone kicked you even lower?"

We'd feel terrible. We'd also never refer to a former girlfriend as "sexual napalm," nor would we drop the N word in a nationally-syndicated interview. But maybe that's just us.
